Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1776715 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Current rating (UL: 15 A minimum), voltage rating (UL: 300 V minimum)
Mechanical Compatibility: 4-position configuration, 5.00mm pitch, 90° right-angle orientation, through-hole mounting
Functional Design: Male pins with 4-side shrouded housing, solder termination
Regulatory Compliance: UL94 V-0 flammability rating, ROHS3 compliance, EAR99 classification
Physical Dimensions: Contact tail length (0.138" / 4.60mm), insulation height within tolerance range

The TE Connectivity AMP Connectors part 796644-4 meets all substitution criteria across these parameters and is classified as a direct equivalent.

Engineering Selection Recommendations

Both the Phoenix Contact 1776715 and TE Connectivity 796644-4 are active production components with full regulatory compliance. Selection between these parts should be based on:

Availability: TE Connectivity 796644-4 maintains higher inventory levels (29,492 units) compared to Phoenix Contact 1776715 (995 units)
Supply Chain Continuity: Both parts carry ROHS3 compliance and EAR99 classification, ensuring equivalent regulatory standing
Certification Status: Both components meet UL94 V-0 flammability requirements and carry identical electrical ratings
Housing Material Variation: Phoenix Contact uses Polybutylene Terephthalate (PBT); TE Connectivity uses Polyamide (PA66). Both materials meet UL94 V-0 requirements and are functionally equivalent for this application
Insulation Height Tolerance: Phoenix Contact insulation height is 0.339" (8.61mm); TE Connectivity is 0.329" (8.36mm). Both dimensions are within acceptable mechanical tolerance for board-level compatibility

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 796644-4 be used as a direct replacement for Phoenix Contact 1776715 on existing PCBs?

A: Yes. Both components share identical pitch (5.00mm), position count (4), orientation (90° right angle), contact tail length (4.60mm), and electrical ratings (15A UL, 300V UL). The insulation height difference (0.339" vs 0.329") falls within standard mechanical tolerance for through-hole mounting and does not affect board-level compatibility.

Q: Are there differences in housing material between these parts?

A: Yes. Phoenix Contact 1776715 uses Polybutylene Terephthalate (PBT) housing, while TE Connectivity 796644-4 uses Polyamide (PA66). Both materials meet UL94 V-0 flammability classification and are functionally equivalent for electrical and mechanical performance in this application.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in: position count (4), pitch spacing (5.00mm), orientation (90° right angle), mounting type (through hole), termination method (solder), electrical ratings (15A/300V UL minimum), shrouded male pin design, and regulatory compliance (UL94 V-0, ROHS3).

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both Phoenix Contact 1776715 and TE Connectivity 796644-4 carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there any operating temperature differences?

A: Phoenix Contact 1776715 does not specify an operating temperature range in the provided data. TE Connectivity 796644-4 specifies -40°C to 110°C. For applications requiring confirmed temperature performance, verify the Phoenix Contact specification with the manufacturer.
